ガラス粒子充てんポリエステル樹脂のクリープ

抄録

The effect of glass volume fraction and Young's moduli of the constituents on the creeps of polyester resin filled with glass fiber particles in the deformation region in which the samples behave as a linear viscoelastic materials were studied by using elastic theory of isotropic heterogeneous elastic body.
The variation in the creep curve with time is pertinewt only to the creeps of resin, therefore by substituting the value of creep compliance for Young's modulus of the resin, we can deduce creep compliance of FRP filled with rigid particles.
The creep compliance of FRP calculated by using a linear viscoelastic operator shows good agreement with the measured value.
